The perimeter of a television screen is 94 inches it is 17 inches tall how wide is it
Nadya [2.5K]
<h3>Answer:  30 inches</h3>

==========================================================

Explanation:

x = unknown width

For this rectangle, there are 2 sides of length x, and 2 sides of length 17.

The perimeter is P = 2x+2*17 = 2x+34

Set this equal to the given perimeter (94) and solve for x.

2x+34 = 94

2x = 94-34

2x = 60

x = 60/2

x = 30

The TV is 30 inches wide

2006 years old.

So it is (1 - 0.65) * 5730

= 2005.5 years old.
